FAQ

What is the maximum operating frequency of the R7F7015823AFP-C#AA3?

The R7F7015823AFP-C#AA3 operates at a maximum CPU frequency of 160 MHz using its RH850 G3KH core. This speed is achievable under full ASIL-B safety monitoring with dual-core lockstep enabled and all voltage/temperature conditions within AEC-Q100 Grade 1 specifications (−40°C to +125°C). The PLL supports multiple clock domains, including separate 160 MHz core, 80 MHz peripheral, and 40 MHz ADC clocks, all derived from a single external crystal or oscillator input.

Does the R7F7015823AFP-C#AA3 support Ethernet AVB, and what physical layer does it require?

Yes, the R7F7015823AFP-C#AA3 integrates a 100BASE-T1 Ethernet AVB controller compliant with IEEE 802.1Qbv and 802.1AS standards. It requires an external 100BASE-T1 PHY IC (e.g., Broadcom BCM8981x or NXP TJA110x) connected via RMII-like differential signaling. The MCU provides ETXD0/ERXD0 pins for the PHY interface, with hardware timestamping and time-synchronized packet scheduling built into the MAC layer - essential for deterministic chassis control networks.

What safety certifications apply to the R7F7015823AFP-C#AA3?

The R7F7015823AFP-C#AA3 is certified to AEC-Q100 Grade 1 and supports ISO 26262 ASIL-B at the hardware level. Its safety mechanisms include dual-core lockstep comparison, memory protection unit (MPU), clock frequency monitor (CFM), independent watchdog timer (IWDG), voltage supervisor, and built-in self-test (BIST) for flash and SRAM. Renesas provides ASIL-B safety manual, FMEDA report, and safety analysis documentation specifically for the R7F7015823AFP-C#AA3 variant, not just the generic RH850/F1K family.

How many CAN FD channels does the R7F7015823AFP-C#AA3 integrate, and what is their maximum bit rate?

The R7F7015823AFP-C#AA3 integrates four independent CAN FD controllers, each supporting data bit rates up to 5 Mbps and nominal bit rates up to 1 Mbps. All channels support ISO 11898-1:2015 and ISO 11898-5:2018, including flexible data-length (up to 64 bytes), CRC-17/21, and bit-rate switching. Each channel has dedicated message RAM with configurable TX/RX buffers and hardware filtering - enabling simultaneous handling of powertrain, chassis, and body CAN FD networks without CPU intervention.

What package type and pin count does the R7F7015823AFP-C#AA3 use?

The R7F7015823AFP-C#AA3 uses a 176-pin LQFP package measuring 24 mm × 24 mm with 0.5 mm pin pitch and an exposed thermal pad. This package is optimized for automotive PCB assembly and thermal dissipation in engine bay environments. Pin assignments follow Renesas' standardized RH850/F1K pinout layout, with dedicated power domains (VDD_1P2_CORE, VDD_3P3_IO, VDDA), multiple ground planes, and ESD-protected I/Os meeting ISO 10605 Level 4 requirements.
